Can a Christian prove to me that their god exists and that he is he omnipotent, omniscient, omnibenevolent person. First round acceptance. Second round he/she gets questions from me then replys. Third round he/she questions me then I answer. last round general ending. No new arguments on the last round. The bible is the claim of god not evidence of him.

First I would like to thank my Lord and Savior Jesus Christ as well as thank my opponent for setting up this debate.

The ontological argument:

1: It is possible that a maximally great being (God) exists.
2: If it is possible that God exists, he exists in some possible world.
3: If God exists in some possible world, He exists in every possible world.
4: If God exists in every possible world, He exists in the actual world.
5: Therefore, God exists in the actual world
6: Therefore, God exists
7: Therefore, a maximally great being exists.

When philosophers talk of possible worlds, they just mean the way the world might have been. A possible world is not a planet or universe. It is just a world description. The actual world is the description that is true. Other possible worlds are descriptions that might have been true, but are not in fact true. To say that something exists in some possible world is to say that there is some description of reality which includes that entity. To say that something exists in every possible world is to say that no matter which description is true, the entity will be included in that description. We can use unicorns as an example. Unicorns do not in fact exists, but there is some possible world in which unicorns exists. There are many mathematicians that think numbers exists in every possible world. That is to say they exists necessarily. God is the greatest conceivable being. If you could conceive of anything greater than God, then that would be God. What would such a being be like? He would be all-powerful, all-knowing, all-good, and he would exists in every logically possible world. Let's look at the implications of this. If Gods existence is even possible, then if follows that God must exist. If a maximally great being exists in any possible world, it exists in all of them. That's part of what it means to be maximally great. So if Gods existence is even possible, he exists in every possible world, including the actual world.

The atheist has to maintain that it is actually impossible for God to exist. The atheist has to say that the concept of God is not even possible in any possible world. Take for example a married bachelor. There is no possible world in which a married bachelor exists. My opponent would have to show that God is something like a married bachelor, not existing in any possible world. The problem is that God does not seem to be incoherent in that way. The idea that a being is all-powerful, all-knowing, all-good, and exists in every possible world is coherent.

It's a shame that most of the debates about the existence of God involve a reductionist view of Him as omnipotent, omniscient, and omni-benevolent. The only time I ever think about God in those terms is when I am talking to atheists. There are so many more descriptive and illustrative metaphors that are much more relavant to the actual Christian walk: Father, Shepherd, Lover, Friend, Savior, Teacher, Guide.

The faceless, characterless, sterile "omni" God of apologetic debates is so far removed from the personal God of the Bible which billions of His children lean upon daily for strength and peace and comfort and joy, that these debates end up being largely academic. Even a slam-dunk argument from the atheist often evokes no more than a "well, I don't believe in *that* God either."

Unfortunately, the "omni" God description is so much easier to argue about than something more experiential like "the Lover of my Soul." So, I guess we'll keep seeing these.
